# lime-qrcode 二维码 |
||||
|
- 一款全平台通用的二维码生成插件，支持uniapp/uniappx(web,ios,安卓) |
||||
|
- uvue 需要导入[lime-qrcodegen](https://ext.dcloud.net.cn/plugin?id=15838) |
||||
|
|
||||
|
## 使用 |
||||
|
- 导入插件后直接使用 |
||||
|
- uvue 需要导入**[lime-qrcodegen](https://ext.dcloud.net.cn/plugin?id=15838)** |
||||
|
|
||||
|
#### 基础使用 |
||||
|
|
||||
|
```html |
||||
|
<l-qrcode value="http://lime.qcoon.cn" /> |
||||
|
``` |
||||
|
|
||||
|
|
||||
|
#### ICON |
||||
|
- 带 Icon 的二维码 |
||||
|
|
||||
|
```html |
||||
|
<l-qrcode value="https://limeui.qcoon.cn" size="300rpx" icon="/static/logo.png" iconSize="70rpx"></l-qrcode> |
||||
|
``` |
||||
|
|
||||
|
#### 颜色 |
||||
|
- 通过设置 `color` 自定义二维码颜色，通过设置 `bgColor` 自定义背景颜色。 |
||||
|
|
||||
|
```html |
||||
|
<l-qrcode value="https://limeui.qcoon.cn" size="300rpx" color="rgb(82,196,26)"></l-qrcode> |
||||
|
<l-qrcode value="https://limeui.qcoon.cn" size="300rpx" color="rgb(22,119,255)" bgColor="rgb(245,245,245)"></l-qrcode> |
||||
|
``` |
||||
|
|
||||
|
#### 纠错比例 |
||||
|
- 通过设置 `errorLevel` 调整不同的容错等级。 |
||||
|
|
||||
|
```html |
||||
|
<l-qrcode value="img10.360buyimg.com/img/jfs/t1/182127/16/37474/11761/64659c31F0cd84976/21f25b952f03a49a.jpg" size="300rpx" errorLevel="H"></l-qrcode> |
||||
|
``` |
||||
|
|
||||
|
#### 生成图片 |
||||
|
- 1、通过调用插件的`canvasToTempFilePath`方法生成图片。 |
||||
|
|
||||
|
```html |
||||
|
<image v-if="image" :src="image" style="width: 300rpx;" mode="widthFix"></image> |
||||
|
<l-qrcode ref="qrcodeRef" value="https://limeui.qcoon.cn" size="300rpx" icon="https://img10.360buyimg.com/img/jfs/t1/182127/16/37474/11761/64659c31F0cd84976/21f25b952f03a49a.jpg" iconSize="70rpx"></l-qrcode> |
||||
|
<button @click="onClick">生成图片</button> |
||||
|
``` |
||||
|
```js |
||||
|
// vue3 |
||||
|
const qrcodeRef = ref(null) |
||||
|
const onClick = () => { |
||||
|
if(!qrcodeRef.value) return |
||||
|
qrcodeRef.value.canvasToTempFilePath({ |
||||
|
success(res) { |
||||
|
image.value = res.tempFilePath |
||||
|
console.log('success:::', res) |
||||
|
}, |
||||
|
fail(err) { |
||||
|
console.log('err:::', err) |
||||
|
} |
||||
|
}) |
||||
|
} |
||||
|
|
||||
|
// vue2 |
||||
|
const el = this.$refs['qrcodeRef'] |
||||
|
el.canvasToTempFilePath({ |
||||
|
success:(res)=>{ |
||||
|
this.image = res.tempFilePath |
||||
|
}, |
||||
|
fail(err) { |
||||
|
console.log('err:::', err) |
||||
|
} |
||||
|
}) |
||||
|
|
||||
|
// uvue |
||||
|
const el:LQrcodeComponentPublicInstance = this.$refs['qrcodeRef'] as LQrcodeComponentPublicInstance |
||||
|
el.canvasToTempFilePath({ |
||||
|
success:(res: TakeSnapshotSuccess)=>{ |
||||
|
this.image = res.tempFilePath |
||||
|
}, |
||||
|
fail(err: TakeSnapshotFail) { |
||||
|
console.log('err:::', err) |
||||
|
} |
||||
|
}) |
||||
|
``` |
||||
|
|
||||
|
- 2、通过设置`useCanvasToTempFilePath`在`success`事件里接收图片地址 |
||||
|
|
||||
|
```html |
||||
|
<image v-if="image" :src="image" style="width: 300rpx;" mode="widthFix"></image> |
||||
|
<l-qrcode useCanvasToTempFilePath @success="success" value="https://limeui.qcoon.cn"></l-qrcode> |
||||
|
``` |
||||
|
```js |
||||
|
const image = ref(null) |
||||
|
const success = (img) => { |
||||
|
image.value = img |
||||
|
} |
||||
|
``` |
||||
|
|
||||
|
### 关于vue2的使用方式 |
||||
|
- 插件使用了`composition-api`, 如果你希望在vue2中使用请按官方的教程[vue-composition-api](https://uniapp.dcloud.net.cn/tutorial/vue-composition-api.html)配置 |
||||
|
- 关键代码是: 在main.js中 在vue2部分加上这一段即可 |
||||
|
|
||||
|
```js |
||||
|
// main.js vue2 |
||||
|
import Vue from 'vue' |
||||
|
import VueCompositionAPI from '@vue/composition-api' |
||||
|
Vue.use(VueCompositionAPI) |
||||
|
``` |
||||
|
另外插件也用到了TS，vue2可能会遇过官方的TS版本过低的问题,找到HX目录下的`compile-typescript`目录 |
||||
|
```cmd |
||||
|
// \HBuilderX\plugins\compile-typescript |
||||
|
yarn add typescript -D |
||||
|
- or - |
||||
|
npm install typescript -D |
||||
|
``` |
||||
|
|
||||
|
### 查看示例 |
||||
|
- 导入后直接使用这个标签查看演示效果 |
||||
|
|
||||
|
```html |
||||
|
// 代码位于 uni_modules/lime-qrcode/compoents/lime-qrcode |
||||
|
<lime-qrcode /> |
||||
|
``` |
||||
|
|
||||
|
### 插件标签 |
||||
|
- 默认 l-qrcode 为 component |
||||
|
- 默认 lime-qrcode 为 demo |
||||
|
|
||||
|
|
||||
|
|
||||
|
## API |
||||
|
|
||||
|
### Props |
||||

| 参数 | 说明 | 类型 | 默认值 | |
||||
|
| --------------------------| ------------------------------------------------------------ | ---------------- | ------------ | |
||||
|
| value | 扫描后的文本 | <em>string</em> | `-` | |
||||
|
| icon | 二维码中图片的地址 | <em>string</em> | `-` | |
||||

success: (res) => { |
||||
|
exif.getData(res.tempFiles[0], function() { |
||||
|
let tagj = exif.getTag(this, "GPSLongitude"); |
||||
|
let Orientation = exif.getTag(this, 'Orientation'); |
||||
|
console.log(tagj, Orientation) |
||||
|
}) |
||||
|
} |
||||
|
}) |
||||
|
``` |
||||
|
|
||||
|
#### selectComponent |
||||
|
- 获取页面或当前实例的指定组件，会在页面或实例向所有的节点查找（包括子组件或子子组件） |
||||
|
- 仅vue3，vue2没有测试过 |
||||
|
|
||||
|
```js |
||||
|
// 当前页面 |
||||
|
const page = getCurrentPage() |
||||
|
selectComponent('.custom', {context: page}).then(res => { |
||||
|
}) |
||||
|
``` |
||||
|
|
||||
|
|
||||
|
#### createAnimation |
||||
|
- 创建动画，与uni.createAnimation使用方法一致，只为了抹平nvue |
||||
|
|
||||
|
```html |
||||
|
<view ref="ball" :animation="animationData"></view> |
||||
|
``` |
||||
|
```js |
||||
|
const ball = ref(null) |
||||
|
const animation = createAnimation({ |
||||
|
transformOrigin: "50% 50%", |
||||
|
duration: 1000, |
||||
|
timingFunction: "ease", |
||||
|
delay: 0 |
||||
|
}) |
||||
|
|
||||
|
animation.scale(2,2).rotate(45).step() |
||||
|
// nvue 无导出数据，这样写只为了平台一致， |
||||
|
// nvue 需要把 ref 传入，其它平台不需要 |
||||
|
const animationData = animation.export(ball.value) |
||||
|
``` |
||||
|
|
||||
|
|
||||
|
## composition-api |
||||
|
- 因本人插件需要兼容vue2/vue3，故增加一个vue文件,代替条件编译 |
||||
|
- vue2需要在main.js加上这一段 |
||||
|
```js |
||||
|
// vue2 |
||||
|
import Vue from 'vue' |
||||
|
import VueCompositionAPI from '@vue/composition-api' |
||||
|
Vue.use(VueCompositionAPI) |
||||
|
``` |
||||
|
|
||||
|
```js |
||||
|
//使用 |
||||
|
import {computed, onMounted, watch, reactive} from '@/uni_modules/lime-shared/vue' |
||||
|
``` |
||||
|
|
||||
|
|
||||
|
## Hooks |
||||
|
#### useIntersectionObserver |
||||
|
- 使用 Intersection Observer 观察元素可见性的钩子函数 |
||||
|
|
||||
|
```html |
||||
|
<div class="target"> |
||||
|
<h1>Hello world</h1> |
||||
|
</div> |
||||
|
``` |
||||
|
|
||||
|
```js |
||||
|
// options 接口可传的参数，若在插件里context为必传 |
||||
|
interface UseIntersectionObserverOptions { |
||||
|
root ?: string; // 观察器的根元素选择器字符串 |
||||
|
rootMargin ?: { |
||||
|
top ?: number; // 根元素顶部边距 |
||||

bottom ?: number; // 根元素底部边距 |
||||
|
left ?: number; // 根元素左侧边距 |
||||
|
right ?: number; // 根元素右侧边距 |
||||
|
}; // 根元素的边距 |
||||
|
thresholds ?: any[]; // 交叉比例数组，用于指定何时触发回调函数 |
||||
|
context ?: any; // 上下文对象，用于指定观察器的上下文 |
||||
|
initialRatio ?: number; // 初始的交叉比例 |
||||
|
observeAll ?: boolean; // 是否同时观察所有交叉对象 |
||||
|
} |
||||
|
const options: UseIntersectionObserverOptions = { |
||||
|
rootMargin: {top: 44}, |
||||
|
context: this |
||||
|
} |
||||
|
const {stop} = useIntersectionObserver('.target', (result) => { |
||||
|
|

|
}, options) |
